I can't seem to find a part number for the coolant temp sensor. The one that came in is larger than the one I have. Same Style and Connection but the one that came in looks to be 1/2 while the one I need appears to be 3/8. Any part number on the 3/8 temp sensor? Appreciate your feedback.

The fuel lines are rotted both the feed and return, I am planning in replacing it with rubber fuel injection line but had a question regarding the rotted ends. I know there is a kit available to replace with factory but due to cost and the time to replace, much easier/cheaper to replace with rubber. Are there repair ends available to fit this coupler? The metal part of the line near the tank is rotted and am looking for a replacement so I can install and attach the hose.
